I tion' is the provision of feeding means for use with a feedingconveyer, whereby a conveyer may automatically feed itself or pick upthe material to be conveyed. Another object is the provision of acombined excavating and conveying member whereby material may be fed toa reciprocating conveyer in response to the reciprocation of theconvey'er. Another object is the provision of means for extending such aconveyor and feed member, in order to permit prolonged feeding withoutfrequent adjustment. Another object is the provision of articulatingmeans for permitting lateral movement of the feeder and conveyer and ofrelative movement, lateral and otherwise, of the feeder and the varioussections of the conveyer. I

Other objects will appear from timeto time in the course of thespecification and claims We illustrate our invention more or' lessdiagrammatically in the accompanying drawings, wherein- Figure 1 is avertical longitudinal section of a typical conveyor;

Figure 2 is a similar section, in cont-1nua-. ac tion of. Figure 1,illustrating the feeding member as applied to the conveying member;

Whereas we do not wish-to limit ourselves to the particular employmentof the feeding member herein shown, or to any particular conveyer, it isherein illustrated as employed so with a reciprocating or shakingconveyor of the type wherein theconveyer is reciprocated in oppositedirections at different speeds, for example, with a slow forwardmovement and a rapid rearward movement.- 'Referring for example toFigures 1 and 2, A indicates the section on the line 6-6 of 1826.

, B is a conveyor trough or chute which mav be reci ers B, which restupon track members 13 and support the upper track members B upon thetrough B.

C diagrammatically illustrates any suitable reciprocating means for saidtrough, includmg the crank arm C Referring to Figures 2 and 3, weillustrate the trou h B as having secured to the forward en of theforward section of the feeder member be understood that we may employany suitable number of trough sections 'B, additional. sections beinginserted as the work progresses.

The securing means between the feeding member andthe end of the trough Bshown in detail in Figures 4, 5 and 6, are asfollows: Secured tothebottom of the trough B is a reinforcing plate D which terminates at theends in eye ets or expanded portions D apertured as at D to receive themembers D. The members D are shouldered as at D and continue as reducedportions D screw threaded as at D. D are lock nuts, which serve to drawthe members D against the rear face or edge of the eyelet D. A

- The feeder member, generally indicated as includes a lower trough E.The feeding member consists preferably of two separate troughs E and Ethe upper trough E being in slidable relation with the lower trough E,there being-no fixed connection between the trough E plate E sEacedbeneath which is the bottom plate Between E- andE may be any suitablespacer or, filler E the assembly and the conveyer section B. At the rearend of the trough Eis a reinforcing procated for example upon therollgenerally indicated as X. It will be ng bolted together for exampleby the bolts or rivets E P tom of the trough E and E is any suitablepivot member or pin E- provided with a washer E and a securing pin EPivotd for rotation about'itin a horizontal plane, andin part containedbetween the plates E assing through the hotand through the plates E andE is the armfE having at its ends shoulders E be 0nd which outwardlyproject the cylindrica tions E Pivotedupon each such cylindrical memberE is the connecting member D por- 1 which is confined for example by thewasher E and the securin pin -E As regards the dc vancing the uppertrough E in relation to the lower trough E. We may employ any suitablerack and pinion connection between the two including for example therack G on one member and the pinion G on the other member and the leverGr .adapted to control them.

The lower trough E of the feeder is supported upon the ground in thefollowing manner: The member J is a transverse slide or runner whichengages the ground and permits easy lateral movement of the feedingmember. The trou h E is supported thereupon for example y means of thedownwardlv depending members J which are in slidable engagement withthe'shoe J. When the feeding member is in anygivenfired po-.. sition themember J serves as a stationary support across which slide the members JArticulating means as employed between the conveyer B and'feeder memberX may'be used between the trough sections B as shown 1* in Figure 3.

It will be realized that whereaswe have-described and shown a practicaland operative device that nevertheless many changes might be made in thesize, shape, number and dispositionof parts without departing from thespirit of our invention. We therefore wish our description and drawingsto be 'taken as in a broad sense illustrative and diagramma'tic ratherthan as limiting us to our spe-- cific showing.

"The use and operation of ourinvention are as follows:

' Reciprocating conveyers of the type herein shown are already known inthe art, namely, conveyers which may be reciprocated at differentvelocities in oppositedirections. in order to cfonvey material fed tothem: Such conveyors may be employed for many .pur-

poses and may for example be employed in mining. Such a conveyer when soemployed may be advanced from a given location by the insertion ofadditionalconveyer sections as the shaft is lengthened, all suchsections formmg'a single conveyer, reciprocated from a single powersource. The material to be conveyed may be shot down from the end of theshaft or otherwise accumulated and is generally divided into lumps andparticles of varying size. Upon the forward end of the conveyer ismounted a feeding member which is adapted to be thrust by the forwardmovement of the conveyer into the pile of material to. be conveyed.The'slow rearward movement of the feeding member conveys away thematerial received upon it as a result of the rapid forward thrust.

As the face of the material bein fed re- K oedes, the upper trough isadvance in relaedi g member" 'roper we may provideany suitable means orad vertical axes.

tion to the lower, until it has advanced to such a. distance that it isnecessary to withdraw it and to insert a new section of the conveyer B.In operating against a laterally extended face, or along a tortuouspassage it isimportant that the conveyer as a whole be articulated, andeven more important that the feeding member at the end of the conveyerbe articulated for free ,lateral movement as well as for movement abouta vertical pivot. Thus the entire assembly may be advanced along acrooked passage and up and down various floor levels and the feedingmember at the end of the conveyer may be swung laterally to feed from aface of considerable width. We have provided a peculiarly flexible androbust articulating means for the feeder and conveyer assembly hereindescribed and shown. In order to permit the'easy lateral movement of thefeeding section we rovide a supporting ground contacting shoe whichserves as a runner to support the feeder and to permitit to be swungabout a vertical pivot. During the normal operation of conveyer andfeeder the feeder, can reciprocate freely in relation to the runner'J,with which it is placed in slidable engagement by means of thedownwardly extending -supporting members J We claim: 1., In a selffeeding conveyer, a conveyer trough and means for imparting to it aconveying reciprocation, a-feeding member at the end of said trough, anarm. pivoted to said "trough, intermediate its endS for rotation about agenerally vertical axis, connectingmembers extending from the ends ofsaid arm to said feeding member'and rotatable about the endsof said arm.

feeding member secured thereto and adapted to move in unison with it andto deliver material direct-1y thereto, said digging member be ingmounted, in relation to said trough, to permit its rotation about bothhorizontal and 3. Ina- 'self-feedin conveyer, an articulated conveyertroug and means for imparting to it a conveying reciprocation, a feedingmember at the receiving end of said trough, an arm (pivoted to saidtrough, intermediate the en 5 of such arm, for rotation about agenerally vertical axis, connecting members extending from the ends ofsaid arm and rotatable thereabout, and afeeding member associated withsaid connecting members.
